Description

内燃機関制御回路及び内燃機関制御方法Internal combustion engine control circuit and internal combustion engine control method
　本発明は、内燃機関を制御する内燃機関制御回路及び内燃機関制御方法に関する。 The present invention relates to an internal combustion engine control circuit for controlling an internal combustion engine and an internal combustion engine control method.
　従来から、エンジン等の内燃機関の電力供給源として、バッテリの他に、キャパシタを用いることが知られている（例えば、特開２０１０－０８３１７８号、特開２０１１－０４７３８０号、特開２０１０－２５９１４７号及び特開２００９－１８０１２５号参照）。また、バッテリの電圧が低く、セルモータを始動させることができない場合には、二輪車のキック等からなる外部駆動装置を駆動することでエンジン等の内燃機関を始動することも知られている。 Conventionally, it is known to use a capacitor in addition to a battery as a power supply source of an internal combustion engine such as an engine (for example, JP 2010-083178, JP 2011-047380, JP 2010-259147, A). No. and JP 2009-180125 A). It is also known to start an internal combustion engine such as an engine by driving an external drive device such as a two-wheeled vehicle kick when the battery voltage is low and the cell motor cannot be started.
　なお、バッテリを用いたシステムとしては、図３に記載したようなものを挙げることができる。図３に示すように、バッテリＢに接続された内燃機関制御回路２００は、負荷１３１を制御する負荷制御回路１３０と、発電機１４１で生成された電流から整流電流を生成する整流回路１４０と、セルモータ１４６を駆動させる駆動回路１４５と、これら負荷制御回路１３０、整流回路１４０及び駆動回路１４５に接続されてこれらを制御する制御部１５０とを備えている。 As a system using a battery, the system shown in FIG. 3 can be cited. As shown in FIG. 3, the internal combustion engine control circuit 200 connected to the battery B includes a load control circuit 130 that controls the load 131, a rectifier circuit 140 that generates a rectified current from the current generated by the generator 141, A drive circuit 145 for driving the cell motor 146 and a control unit 150 connected to and controlling the load control circuit 130, the rectifier circuit 140, and the drive circuit 145 are provided.
　発電機とキャパシタが単純に接続された状態で、二輪車のキック等からなる外部駆動装置を駆動してエンジン等の内燃機関を始動させると、キャパシタの電圧が低いときは外部駆動装置を駆動させることによって発電機で生成された電力の全てがキャパシタの充電に使用されてしまい、キャパシタが充電されるまで内燃機関を始動することができないという問題が生じうる。 When an external drive device such as a kick of a motorcycle is driven to start an internal combustion engine such as an engine with a generator and a capacitor simply connected, the external drive device is driven when the voltage of the capacitor is low As a result, all of the electric power generated by the generator is used for charging the capacitor, which may cause a problem that the internal combustion engine cannot be started until the capacitor is charged.
　この点、リレー等のスイッチで発電機からキャパシタを一度切り離した状態で外部駆動装置を駆動して内燃機関を始動し、内燃機関が始動された後で、キャパシタを充電するために発電機にキャパシタを接続することも考えられる。しかしながら、このような場合には、発電機にキャパシタを接続した時にキャパシタへ大きな充電電流が急激に流れてしまう可能性がある。そして、このようにキャパシタへ大きな充電電流が急激に流れてしまうと、ＥＣＵ等の制御部の電圧が低下してしまい、内燃機関が停止してしまうことが生じうる。 In this regard, the external drive device is driven with the capacitor once disconnected from the generator with a switch such as a relay to start the internal combustion engine. After the internal combustion engine is started, the capacitor is charged to the generator to charge the capacitor. Can also be considered. However, in such a case, when a capacitor is connected to the generator, a large charging current may flow rapidly to the capacitor. If a large charging current flows suddenly to the capacitor in this way, the voltage of the control unit such as the ECU may decrease, and the internal combustion engine may stop.
　本発明は、二輪車のキック等からなる外部駆動装置とキャパシタを備えた装置において、外部駆動装置を駆動することで内燃機関を即座に始動することができ、かつ、制御部の電圧低下によって内燃機関が停止しない内燃機関制御回路及び内燃機関制御方法を提供する。 The present invention is an apparatus having an external drive device such as a kick of a two-wheeled vehicle and a capacitor, and can immediately start the internal combustion engine by driving the external drive device. An internal combustion engine control circuit and an internal combustion engine control method are provided.

A capacitor for charging the power generated by the generator generated by the driving force generated by the internal combustion engine and the driving force generated by driving the external driving device and supplying the charged power to the cell motor Detecting the voltage;
Charging only the capacitor by controlling supply of the power generated by the generator to the capacitor based on the voltage of the capacitor, and
The current generated by the generator is made constant by a constant current circuit, and the constant current charges only the capacitor.
　本発明においては、発電機とキャパシタの間に定電流回路が設けられており、二輪車のキック等からなる外部駆動装置を駆動することによって発電機で生成された電流は、定電流回路で小さな定電流となってキャパシタに流れてキャパシタを充電する。このため、外部駆動装置を駆動することで生成された電力の全てがキャパシタの充電に使用されてしまうことがなく、エンジン等の内燃機関を即座に始動することができる。また、そもそもキャパシタが定電流回路を介して常時発電機に接続されていることから、発電機にキャパシタを接続した時にキャパシタへ大きな充電電流が急激に流れてしまうことはない。 In the present invention, a constant current circuit is provided between the generator and the capacitor, and the current generated by the generator by driving an external driving device such as a kick of a two-wheeled vehicle is a small constant current circuit. The current flows into the capacitor and charges the capacitor. For this reason, all the electric power generated by driving the external drive device is not used for charging the capacitor, and an internal combustion engine such as an engine can be started immediately. In the first place, since the capacitor is always connected to the generator via the constant current circuit, a large charging current does not flow suddenly to the capacitor when the capacitor is connected to the generator.

Embodiments of an internal combustion engine control circuit and an internal combustion engine control method according to the present invention will be described below with reference to the drawings. Here, FIG. 1 is a diagram for explaining an embodiment of the present invention.
　本実施の形態の内燃機関制御回路１００は、エンジン（内燃機関）６０を制御するための回路である。図１に示すように、本実施の形態の内燃機関制御回路１００には、電力を蓄えることができるキャパシタＣ、発電することができる発電機４１、エンジン６０を始動させるセルモータ４６及びランプ等の負荷３１に接続されている。本実施の形態では、バッテリは用いられず、電力を蓄えるのはキャパシタＣのみであり、発電機４１で発電される電力はキャパシタＣのみに充電される。他方、キャパシタＣに充電された電力は、当該キャパシタＣに接続された負荷３１、セルモータ４６等に供給されて、これら負荷３１、セルモータ４６等を駆動させる。 The internal combustion engine control circuit 100 of the present embodiment is a circuit for controlling the engine (internal combustion engine) 60. As shown in FIG. 1, the internal combustion engine control circuit 100 of the present embodiment includes a capacitor C that can store electric power, a generator 41 that can generate electric power, a cell motor 46 that starts the engine 60, and a load such as a lamp. 31 is connected. In the present embodiment, a battery is not used, and only the capacitor C stores electric power, and the electric power generated by the generator 41 is charged only in the capacitor C. On the other hand, the electric power charged in the capacitor C is supplied to the load 31, the cell motor 46 and the like connected to the capacitor C, and drives the load 31, the cell motor 46 and the like.
　内燃機関制御回路１００は、キャパシタＣの電圧を検出する電圧検出回路２０と、電圧検出回路２０で検出されたキャパシタＣの電圧に基づいて、キャパシタＣのみに充電された電力のセルモータ４６、負荷３１等に対する供給を制御し、かつ、発電機４１で発電された電力のキャパシタＣに対する供給を制御してキャパシタＣのみに充電させるＥＣＵ等の制御部５０と、を備えている。なお、電圧検出回路２０及び制御部５０にはキャパシタＣが接続されており、これら電圧検出回路２０及び制御部５０にはキャパシタＣから電力が供給される。 The internal combustion engine control circuit 100 includes a voltage detection circuit 20 that detects the voltage of the capacitor C, a cell motor 46 that is charged only in the capacitor C based on the voltage of the capacitor C detected by the voltage detection circuit 20, and a load 31. And a control unit 50 such as an ECU that controls the supply of the electric power generated by the generator 41 to the capacitor C to charge only the capacitor C. A capacitor C is connected to the voltage detection circuit 20 and the control unit 50, and power is supplied from the capacitor C to the voltage detection circuit 20 and the control unit 50.
　本実施の形態の内燃機関制御回路１００は、発電機４１とキャパシタＣに接続され、発電機４１で生成された電流から定電流を生成して、当該定電流でキャパシタＣのみを充電する定電流回路１０も備えている。発電機４１とキャパシタＣの間には、この定電流回路１０と並列にリレー（請求の範囲の「スイッチ」に該当する。）７０が接続されている。なお、リレー７０とキャパシタＣの間にはヒューズ７５が接続されている。 The internal combustion engine control circuit 100 according to the present embodiment is connected to the generator 41 and the capacitor C, generates a constant current from the current generated by the generator 41, and charges only the capacitor C with the constant current. A circuit 10 is also provided. Between the generator 41 and the capacitor C, a relay (corresponding to “switch” in claims) 70 is connected in parallel with the constant current circuit 10. A fuse 75 is connected between the relay 70 and the capacitor C.
　以下では、本実施の形態の内燃機関制御回路１００で制御させる装置が二輪車である態様を用いて説明する。ただし、これはあくまでも一例である。つまり、本発明の内燃機関制御回路１００は、二輪車以外の装置を制御することもできる。 Hereinafter, a description will be given using a mode in which the device controlled by the internal combustion engine control circuit 100 of the present embodiment is a two-wheeled vehicle. However, this is only an example. That is, the internal combustion engine control circuit 100 of the present invention can also control devices other than motorcycles.
　図１に示すように、本実施の形態のエンジン６０には、エンジン６０を始動するための外部駆動装置６５が連結されている。なお、外部駆動装置６５はたとえばキックであり、セルモータ４６以外の手段でエンジン６０を駆動することができる装置である。 As shown in FIG. 1, an external drive device 65 for starting the engine 60 is connected to the engine 60 of the present embodiment. The external drive device 65 is a kick, for example, and is a device that can drive the engine 60 by means other than the cell motor 46.
　なお、上述した発電機４１は、エンジン６０で生成される駆動力及び外部駆動装置６５が駆動されることで生成される駆動力によって発電される。また、自然放電等によってキャパシタＣの電圧がエンジン６０を始動させるのに必要な始動可能電圧未満となっている場合には、外部駆動装置６５を用いることで、エンジン６０を始動させることができる。 The generator 41 described above is generated by the driving force generated by the engine 60 and the driving force generated when the external driving device 65 is driven. Further, when the voltage of the capacitor C is lower than the startable voltage necessary for starting the engine 60 due to natural discharge or the like, the engine 60 can be started by using the external drive device 65.
　本実施の形態の電圧検出回路２０は、エンジン６０が始動された後もキャパシタＣの電圧の監視を続け、制御部５０は、電圧検出回路２０によって検出されたキャパシタＣの電圧が所定電圧未満のときには、リレー７０をＯＦＦにするよう制御し、電圧検出回路２０によって検出されたキャパシタＣの電圧が所定電圧以上になったときにリレー７０をＯＮにするよう制御する。また、本実施の形態の制御部５０は、キャパシタＣのみに充電された電力をセルモータ４６、負荷３１等に対して供給する際に、リレー駆動回路７１を制御してリレー７０をＯＮにするよう制御する。なお、上述した「所定電圧」としては、例えばエンジン６０が駆動されることで発電機４１で生成される発電電圧（例えば１２Ｖ～１３Ｖ）を用いることができる。 The voltage detection circuit 20 of the present embodiment continues to monitor the voltage of the capacitor C even after the engine 60 is started, and the control unit 50 detects that the voltage of the capacitor C detected by the voltage detection circuit 20 is less than a predetermined voltage. Sometimes, the relay 70 is controlled to be turned off, and the relay 70 is turned on when the voltage of the capacitor C detected by the voltage detection circuit 20 becomes equal to or higher than a predetermined voltage. Further, the control unit 50 of the present embodiment controls the relay drive circuit 71 to turn on the relay 70 when supplying the electric power charged only to the capacitor C to the cell motor 46, the load 31, and the like. Control. As the above-mentioned “predetermined voltage”, for example, a power generation voltage (for example, 12V to 13V) generated by the generator 41 when the engine 60 is driven can be used.
　負荷３１には負荷３１を制御する負荷制御回路３０が接続されている。また、この負荷制御回路３０には制御部５０が接続されており、制御部５０が、動作指令を送ることで負荷制御回路３０は制御される。また、負荷制御回路３０はキャパシタＣに接続されており、キャパシタＣのみに充電された電力で駆動される。 A load control circuit 30 that controls the load 31 is connected to the load 31. Further, a control unit 50 is connected to the load control circuit 30, and the load control circuit 30 is controlled when the control unit 50 sends an operation command. The load control circuit 30 is connected to the capacitor C, and is driven by the electric power charged only in the capacitor C.
　発電機４１には、発電機４１で生成された電流から整流電流を生成する整流回路４０が接続されている。そして、この整流回路４０はキャパシタＣに接続されており、整流回路４０で生成された整流電流がキャパシタＣに供給されてキャパシタＣのみを充電する。 A rectifier circuit 40 that generates a rectified current from the current generated by the generator 41 is connected to the generator 41. The rectifier circuit 40 is connected to the capacitor C, and the rectified current generated by the rectifier circuit 40 is supplied to the capacitor C to charge only the capacitor C.
　セルモータ４６には、セルモータ４６を駆動させる駆動回路４５が接続されている。そして、この駆動回路４５はキャパシタＣに接続されており、エンジン６０の始動時には駆動回路４５はキャパシタＣのみに充電された電力で駆動される。 A driving circuit 45 for driving the cell motor 46 is connected to the cell motor 46. The drive circuit 45 is connected to the capacitor C. When the engine 60 is started, the drive circuit 45 is driven by electric power charged only in the capacitor C.
　なお、整流回路４０及び駆動回路４５の各々には制御部５０が接続されており、当該制御部５０が、動作指令を送ることで整流回路４０及び駆動回路４５を制御する。 A control unit 50 is connected to each of the rectifier circuit 40 and the drive circuit 45, and the control unit 50 controls the rectifier circuit 40 and the drive circuit 45 by sending an operation command.
　ところで、キャパシタＣは、その容量がエンジン６０を始動可能な容量になっている。また、用いられるキャパシタＣの一例としては、スーパーキャパシタを挙げることができる。なお、スーパーキャパシタとは、電気二重層キャパシタの総称である。 By the way, the capacity of the capacitor C is a capacity capable of starting the engine 60. An example of the capacitor C used is a super capacitor. Supercapacitor is a general term for electric double layer capacitors.
　なお、図１では、発電機４１とセルモータ４６は別体になった態様を示しているが、これに限られることはなく、発電機４１がセルモータ４６を兼ねてもよい。また、本実施の形態の発電機４１は単相発電機であってもよいし三相発電機等の多相発電機であってもよい。 In addition, in FIG. 1, although the generator 41 and the cell motor 46 showed the aspect which became a different body, it is not restricted to this, The generator 41 may serve as the cell motor 46. The generator 41 of the present embodiment may be a single-phase generator or a multi-phase generator such as a three-phase generator.
　ところで、本実施の形態で「キャパシタＣのみ」を用いるとしているのは、エンジン６０を始動するための電力供給源としての話であり、エンジン始動後にエンジン６０を駆動するための電力供給源としてキャパシタＣ以外の電力供給源を用いたとしても、本発明の技術的範囲から外れることはない点には留意が必要である。 By the way, “capacitor C only” is used in the present embodiment as a power supply source for starting engine 60, and a capacitor is used as a power supply source for driving engine 60 after engine startup. It should be noted that the use of a power supply source other than C does not depart from the technical scope of the present invention.
　なお、エンジン６０が動作されている際には、定電流回路１０、電圧検出回路２０、負荷制御回路３０、負荷３１、整流回路４０、駆動回路４５、制御部５０、リレー７０、リレー駆動回路７１等は、発電機４１で発電される電力によって駆動されることとなる。 When the engine 60 is in operation, the constant current circuit 10, voltage detection circuit 20, load control circuit 30, load 31, rectifier circuit 40, drive circuit 45, control unit 50, relay 70, relay drive circuit 71 Are driven by the electric power generated by the generator 41.
《作用・効果》
　次に、上述した構成からなる本実施の形態による作用・効果について説明する。 《Action ・ Effect》
Next, the operation and effect of the present embodiment having the above-described configuration will be described.
　本実施の形態の内燃機関制御回路１００では、発電機４１とキャパシタＣの間に定電流回路１０が設けられている。このため、二輪車の外部駆動装置６５を駆動することによって発電機４１で生成された電流は、定電流回路１０を介してキャパシタＣに流れてキャパシタＣを充電する。この結果、外部駆動装置６５を駆動することで発電機４１で発電された電力の全てがキャパシタＣの充電に使用されてしまうことはなく、エンジン６０を即座に始動することができる。 In the internal combustion engine control circuit 100 of the present embodiment, the constant current circuit 10 is provided between the generator 41 and the capacitor C. For this reason, the current generated by the generator 41 by driving the external drive device 65 of the motorcycle flows into the capacitor C via the constant current circuit 10 and charges the capacitor C. As a result, by driving the external drive device 65, not all of the electric power generated by the generator 41 is used for charging the capacitor C, and the engine 60 can be started immediately.
　すなわち、発電機４１とキャパシタＣが単純に接続された態様では、外部駆動装置６５を駆動してエンジン６０を始動させると、外部駆動装置６５を駆動させることによって発電機４１で生成された電力の全てがキャパシタＣの充電に使用されてしまい、キャパシタＣが充電されるまでエンジン６０を始動することができないという問題が生じうる。これに対して、本実施の形態によれば、発電機４１とキャパシタＣの間に、小さな定電流を流す定電流回路１０が設けられていることから、外部駆動装置６５を駆動することで発電機４１で発電された電力の全てがキャパシタＣの充電に使用されてしまうことがなく、このような問題が生じない。 That is, in a mode in which the generator 41 and the capacitor C are simply connected, when the external drive device 65 is driven to start the engine 60, the external drive device 65 is driven to drive the electric power generated by the generator 41. All of this is used to charge the capacitor C, which may cause a problem that the engine 60 cannot be started until the capacitor C is charged. On the other hand, according to the present embodiment, since the constant current circuit 10 for passing a small constant current is provided between the generator 41 and the capacitor C, the external drive device 65 is driven to generate power. All of the electric power generated by the machine 41 is not used for charging the capacitor C, and such a problem does not occur.
　また、本実施の形態では、キャパシタＣが定電流回路１０を介して常時発電機４１に接続されていることから、発電機４１にキャパシタＣを接続した時にキャパシタＣへ大きな充電電流が急激に流れてしまうことはない。 In the present embodiment, since the capacitor C is always connected to the generator 41 via the constant current circuit 10, a large charging current suddenly flows to the capacitor C when the capacitor C is connected to the generator 41. There is no end.
　すなわち、発電機４１で発電された電力の全てがキャパシタＣの充電に使用されてしまうことを防止するために、外部駆動装置６５を駆動してエンジン６０を始動させる際に、リレー等で発電機４１からキャパシタＣを一度切り離した状態でエンジン６０を始動し、エンジン６０が始動された後で、キャパシタＣを充電するために発電機４１にキャパシタＣを接続することも考えられる。しかしながら、このような場合には、発電機４１にキャパシタＣを接続した時にキャパシタＣへ大きな充電電流が急激に流れてしまい、制御部５０の電圧が低下してしまう可能性があり、結果として、エンジン６０が停止してしまうという問題が生じうる。これに対して、本実施の形態では、キャパシタＣが定電流回路１０を介して常時発電機４１に接続されていることから、そもそも、このような問題が生じない。 That is, in order to prevent all the electric power generated by the generator 41 from being used to charge the capacitor C, when the external drive device 65 is driven to start the engine 60, the generator is generated by a relay or the like. It is also conceivable that the engine 60 is started with the capacitor C once disconnected from 41, and the capacitor C is connected to the generator 41 in order to charge the capacitor C after the engine 60 is started. However, in such a case, when the capacitor C is connected to the generator 41, a large charging current may suddenly flow to the capacitor C, and the voltage of the control unit 50 may decrease. There may be a problem that the engine 60 stops. On the other hand, in this embodiment, since the capacitor C is always connected to the generator 41 via the constant current circuit 10, such a problem does not occur in the first place.
　また、本実施の形態では、電圧検出回路２０が、エンジン６０が始動された後もキャパシタＣの電圧の監視を続け、制御部５０が、電圧検出回路２０によって検出されたキャパシタＣの電圧が所定電圧未満のときにはリレー７０をＯＦＦにするよう制御し、電圧検出回路２０によって検出されたキャパシタＣの電圧が所定電圧以上になったときにリレー７０をＯＮにするよう制御する。このため、キャパシタＣの電圧が所定電圧未満のときには、発電機４１で発電された電力による電流を定電流回路１０を介してキャパシタＣに流すことができ、他方、キャパシタＣの電圧が所定電圧以上になったときには、発電機４１で発電された電力による電流をリレー７０を介してキャパシタＣに流すことができる。したがって、キャパシタＣの電圧が所定電圧未満のときには、定電流回路１０によって小さな定電流でキャパシタＣを充電させることができ、他方、キャパシタＣの電圧が所定電圧以上になったときには、リレー７０をＯＮにすることで大きな電流でキャパシタＣを充電させることができ、キャパシタＣの充電効率を高めることができる。 In the present embodiment, the voltage detection circuit 20 continues to monitor the voltage of the capacitor C even after the engine 60 is started, and the control unit 50 sets the voltage of the capacitor C detected by the voltage detection circuit 20 to a predetermined value. When the voltage is less than the voltage, the relay 70 is controlled to be turned off, and when the voltage of the capacitor C detected by the voltage detection circuit 20 becomes equal to or higher than a predetermined voltage, the relay 70 is turned on. For this reason, when the voltage of the capacitor C is less than the predetermined voltage, the current generated by the power generated by the generator 41 can be supplied to the capacitor C through the constant current circuit 10, while the voltage of the capacitor C is equal to or higher than the predetermined voltage. In this case, the current generated by the power generated by the generator 41 can be passed through the capacitor C via the relay 70. Therefore, when the voltage of the capacitor C is less than the predetermined voltage, the constant current circuit 10 can charge the capacitor C with a small constant current. On the other hand, when the voltage of the capacitor C exceeds the predetermined voltage, the relay 70 is turned on. Thus, the capacitor C can be charged with a large current, and the charging efficiency of the capacitor C can be increased.
　また、本実施の形態では、制御部５０が、キャパシタＣのみに充電された電力をセルモータ４６、負荷３１等に対して供給する際に、リレー７０をＯＮにするよう制御する。このため、セルモータ４６、負荷３１等を駆動させる際には、これらセルモータ４６、負荷３１等に大きな電流を供給することができる。 In the present embodiment, the control unit 50 controls the relay 70 to be turned on when supplying the electric power charged only in the capacitor C to the cell motor 46, the load 31, and the like. For this reason, when driving the cell motor 46, the load 31, and the like, a large current can be supplied to the cell motor 46, the load 31, and the like.
　ところで、本実施の形態の内燃機関制御回路１００によれば、発電機４１で発電された電力をキャパシタＣのみに充電し、かつ、キャパシタＣのみに充電された電力によってセルモータ４６に電力を供給してエンジン６０を始動したり負荷３１等に電力を供給したりすることができ、バッテリを用いずキャパシタＣのみを用いることができる。そして、キャパシタＣの寿命はバッテリと比較して長寿命であるため、キャパシタＣを二輪車の交換しやすい場所に設置する必要がなく、キャパシタＣの実装場所が制限されない。 By the way, according to the internal combustion engine control circuit 100 of the present embodiment, the power generated by the generator 41 is charged only in the capacitor C, and the cell motor 46 is supplied with the power charged only in the capacitor C. Thus, the engine 60 can be started or power can be supplied to the load 31 or the like, and only the capacitor C can be used without using a battery. Since the life of the capacitor C is longer than that of the battery, it is not necessary to install the capacitor C in a place where the two-wheeled vehicle can be easily replaced, and the place where the capacitor C is mounted is not limited.
　すなわち、従来のようにバッテリを用いるものでは、バッテリが２～３年程で寿命がきてしまうので、バッテリを定期的に交換する必要がある。このため、バッテリは、二輪車の交換しやすい場所に設置する必要がある。これに対して、本実施の形態によれば、バッテリを用いず、バッテリと比較して長寿命であるキャパシタＣのみを用いることができる。このようにキャパシタＣの寿命が長いことから、キャパシタＣを二輪車の交換しやすい場所に設置する必要がなく、キャパシタＣの実装場所が制限されない。したがって、本実施の形態によれば、二輪車の設計の自由度を高めることができるという、非常な有益な効果を得ることができる。 That is, in the case of using a battery as in the conventional case, since the battery has a life of about 2 to 3 years, it is necessary to replace the battery periodically. For this reason, it is necessary to install the battery in a place where the motorcycle can be easily replaced. On the other hand, according to the present embodiment, it is possible to use only the capacitor C having a longer life than the battery, without using the battery. Since the life of the capacitor C is thus long, it is not necessary to install the capacitor C in a place where the two-wheeled vehicle can be easily replaced, and the mounting location of the capacitor C is not limited. Therefore, according to the present embodiment, it is possible to obtain a very beneficial effect that the degree of freedom in designing a motorcycle can be increased.
　また、上述したように、バッテリの寿命は短いため、従来のようにバッテリを用いた二輪車等の装置ではバッテリを定期的に交換する必要があるが、ユーザ自身がバッテリを交換する際に、バッテリのプラスとマイナスを間違えて接続することがある。このようにバッテリのプラスとマイナスを間違えて接続してしまうと、内燃機関制御回路１００が壊れてしまう。これに対して、本実施の形態の内燃機関制御回路１００によれば、交換する必要の少ないキャパシタＣのみを用いることができるので、このような問題がそもそも発生しない。 In addition, as described above, since the battery life is short, it is necessary to periodically replace the battery in an apparatus such as a two-wheeled vehicle using a battery as in the past, but when the user himself replaces the battery, There are cases where the plus and minus are mistakenly connected. In this way, if the battery is connected with the positive and negative mistakes, the internal combustion engine control circuit 100 is broken. On the other hand, according to the internal combustion engine control circuit 100 of the present embodiment, since only the capacitor C that needs to be replaced can be used, such a problem does not occur in the first place.
　ところで、バッテリとしては鉛バッテリが一般に用いられている。このような鉛バッテリを用いるものでは、鉛による環境への負荷が大きい。本実施の形態では、バッテリ自体を用いないため、鉛バッテリを用いることがない。この結果、本実施の形態によれば、従来技術と比較して、環境への負荷を低減することができる。 Incidentally, a lead battery is generally used as the battery. In the case of using such a lead battery, the load on the environment due to lead is large. In this embodiment, since the battery itself is not used, a lead battery is not used. As a result, according to the present embodiment, it is possible to reduce the load on the environment as compared with the prior art.
第２の実施の形態
　次に、図２により、本発明の第２の実施の形態について説明する。 Second Embodiment Next, the second embodiment of the present invention will be described with reference to FIG.
　第１の実施の形態では、発電機４１とキャパシタＣの間に、定電流回路１０と並列にリレー７０が接続されている態様であった。これに対して、本実施の形態では、このようなリレー７０は設けられておらず、その代わりに、制御部５０が、電圧検出回路２０によって検出されたキャパシタＣの電圧に基づいて、定電流回路１０で生成される定電流の大きさを制御するようになっている。また、本実施の形態では、発電機４１とキャパシタＣの間で、定電流回路１０と並列に接続されたダイオード１５が設けられており、このダイオード１５のカソードが発電機４１に接続され、アノードがキャパシタＣに接続されている。 In the first embodiment, the relay 70 is connected between the generator 41 and the capacitor C in parallel with the constant current circuit 10. On the other hand, in the present embodiment, such a relay 70 is not provided, and instead, the control unit 50 uses a constant current based on the voltage of the capacitor C detected by the voltage detection circuit 20. The magnitude of the constant current generated by the circuit 10 is controlled. In the present embodiment, a diode 15 connected in parallel with the constant current circuit 10 is provided between the generator 41 and the capacitor C. The cathode of the diode 15 is connected to the generator 41, and the anode Is connected to the capacitor C.
　第２の実施の形態において、その他の構成は、第１の実施の形態と略同一の態様となっている。図２に示した第２の実施の形態において、図１に示した第１の実施の形態と同一部分には同一符号を付して詳細な説明は省略する。 In the second embodiment, the other configurations are substantially the same as those in the first embodiment. In the second embodiment shown in FIG. 2, the same parts as those in the first embodiment shown in FIG.
　本実施の形態でも、発電機４１とキャパシタＣの間に定電流回路１０が設けられている。このため、第１の実施の形態と同様に、外部駆動装置６５を駆動することによって発電機４１で発電された電力の全てがキャパシタＣの充電に使用されてしまうことはなく、エンジン６０を即座に始動することができる。 Also in the present embodiment, the constant current circuit 10 is provided between the generator 41 and the capacitor C. For this reason, as in the first embodiment, all of the electric power generated by the generator 41 by driving the external drive device 65 is not used for charging the capacitor C, and the engine 60 is immediately turned on. Can be started.
　また、本実施の形態でも、キャパシタＣが定電流回路１０を介して常時発電機４１に接続されていることから、発電機４１にキャパシタＣを接続した時にキャパシタＣへ大きな充電電流が急激に流れてしまうことはない。 Also in the present embodiment, since the capacitor C is always connected to the generator 41 via the constant current circuit 10, a large charging current suddenly flows to the capacitor C when the capacitor C is connected to the generator 41. There is no end.
　また、本実施の形態では、制御部５０が、電圧検出回路２０によって検出されたキャパシタＣの電圧に基づいて、定電流回路１０で生成される定電流の大きさを制御するようになっている。このため、キャパシタＣの電圧の大きさに応じて定電流回路１０で生成される定電流の大きさを適宜変えることができ、キャパシタＣの充電効率を高めることができる。 In the present embodiment, the control unit 50 controls the magnitude of the constant current generated by the constant current circuit 10 based on the voltage of the capacitor C detected by the voltage detection circuit 20. . For this reason, the magnitude of the constant current generated by the constant current circuit 10 can be appropriately changed according to the magnitude of the voltage of the capacitor C, and the charging efficiency of the capacitor C can be increased.
　また、本実施の形態では、発電機４１とキャパシタＣの間で定電流回路１０と並列に接続されたダイオード１５が設けられており、このダイオード１５のカソードが発電機４１に接続され、アノードがキャパシタＣに接続されている。このため、セルモータ４６、負荷３１等を駆動させる際には、これらセルモータ４６、負荷３１等に大きな電流を供給することができる。 In the present embodiment, a diode 15 connected in parallel with the constant current circuit 10 is provided between the generator 41 and the capacitor C. The cathode of the diode 15 is connected to the generator 41, and the anode is The capacitor C is connected. For this reason, when driving the cell motor 46, the load 31, and the like, a large current can be supplied to the cell motor 46, the load 31, and the like.
　ところで、本実施の形態でも、バッテリを用いずキャパシタＣのみを用いることができるので、第１の実施の形態と同様、キャパシタＣを二輪車の交換しやすい場所に設置する必要がなくキャパシタＣの実装場所が制限されない。また、このようにバッテリを用いないことから、バッテリを交換する際にバッテリのプラスとマイナスを間違えて接続することで内燃機関制御回路１００が壊れてしまうというような問題が発生することもない。さらに、鉛バッテリを用いることもなく、環境への負荷を低減することができる。 By the way, in this embodiment, since only the capacitor C can be used without using a battery, it is not necessary to install the capacitor C in a place where the two-wheeled vehicle can be easily replaced, as in the first embodiment. Location is not limited. In addition, since the battery is not used in this way, there is no problem that the internal combustion engine control circuit 100 is broken when the battery is replaced with the wrong plus or minus of the battery. Furthermore, the load on the environment can be reduced without using a lead battery.
　上記では、ダイオード１５を用いて説明したが、このようなダイオード１５を設ける代わりにリードスイッチ等のスイッチを設けてもよい。このような態様によっても、本実施の形態と同様の効果を奏することができる。 In the above description, the diode 15 is used, but a switch such as a reed switch may be provided instead of providing such a diode 15. Even in such an aspect, the same effects as in the present embodiment can be obtained.
　最後になったが、上述した実施の形態の記載及び図面の開示は、請求の範囲に記載された発明を説明するための一例に過ぎず、上述した実施の形態の記載又は図面の開示によって請求の範囲に記載された発明が限定されることはない。 Lastly, the description of the above-described embodiment and the disclosure of the drawings are merely examples for explaining the invention described in the claims, and the claims are made based on the description of the above-described embodiments or the disclosure of the drawings.
